The coldest recorded temperature in southern Minnesota appeared to be Fairmont, in Martin County, which bottomed out at 25 degrees, according to the National Weather Service. Here's a look at the low temperatures in the region for Thursday morning:

Twin Cities awaits its first freeze

But not all of southern Minnesota saw its first freeze of the season. That's because clouds stuck around longer than expected in the Twin Cities metro, which helped keep temperatures above 32 degrees, the National Weather Service says.

The last time Minneapolis-St. Paul International Airport saw below-freezing temps was April 12, and it may be a little longer until the mercury drops below 32 degrees, according to meteorologist Paul Huttner, who wrote on MPR News' Updraft blog that the Twin Cities will likely go at least another week staying above that mark.

That would make this year one of the longest growing seasons on record, Huttner says. Right now, the growing season (the number of days between the last freezing temperatures in the spring and the first freezing temperatures in the fall) at MSP Airport is at 184 days.

Weekend warmup

After Thursday's cool start, southerly winds will help bring temperatures back into the 50s by the afternoon. Even warmer temperatures are expected for the weekend, with the National Weather Service forecasting temperatures in the 60s and 70s through Monday.

There's a chance for showers and thunderstorms periodically over the next week, especially Saturday, Sunday night and Monday night, the weather service says.
